Is this ok [y/d/N]:

Restart Apache

systemctl restart httpd

Check if PHP correctly installed

Create new file called info.php under /var/www/html directory

nano /var/www/html/info.php

Now paste this line to it

<?php phpinfo(); ?>

Now open web browser and type the server ip address with info.php. For example in my case:

http://10.34.0.215/info.php
